This is my second pregnancy and I had this in my first too but not quite as extreme - I just can’t stop smelling bloody cleaning products. Every few days there’s a new product I’m “into”. I’m 35 weeks and had this since about 28 weeks. So far I have been through
Bouquet zoflora
Pine disinfectant
Furniture polish
Flash floor cleaner
Domestos bleach spray
Bleach
Ace laundry bleach
Hand sanitiser
I absolutely love going out to get new cleaning products with my shopping. I like to read all the different ways you can clean with them.
My top favs at the moment are the ace laundry bleach and hand sanitiser - can’t find any hand gel with the situation but have managed to buy a pack of hand sanitising wipes, can’t stop wiping my face and hands and sniffing them.
I’ve ordered a bottle of isopropyl alcohol from amazon which is the main ingredient that I’m smelling. Will probably put it in a spray bottle for my counter tops 
Every night after I’ve finished cleaning everything up I mop the floor in either bleach or disinfectant and I put a big dollop of it in the sink (not mixed) with boiling water so the smell wafts through, my husband is sick of the smell of chemicals but i can’t get enough.
I also love spraying polish on my radiators then putting them on for half hour so that my living room smells of it.
Does anyone else have this??
